According to a study published in The Lancet, taste loss and smell loss in symptoms of new coronary infections is more specific and longer lasting, which can be the strongest predictor of whether or not they have been infected. Public health authorities around the world are trying to control the spread of the new coronavirus by raising public awareness and tracking contacts, specifically by identifying and isolating people at high risk of contracting the virus, the researchers said.
In many countries, conventional large-scale swab nucleic acid detection capacity is still insufficient. Therefore, in order to reduce the number of infected people in the community, it is important to use a combination of symptoms that quickly identify patients.
Previous reports have shown that, in addition to the most definite high fever and new persistent cough symptoms, loss of smell and taste is a potential predictor of COVID-19.
Users who reported loss of smell and taste in the sample had a new coronary positive rate of 65.03 percent and a negative rate of 21.71 percent, suggesting that people with loss of sense of smell and taste should isolate themselves.
